Found this little greeting on The Blue Room Technical Forum – not sure I can link to it as I think the sub-forum it was posted in is hidden from unregistered members.

I wanted to send some sort of holiday greeting to my friends and colleagues, but it is difficult in today’s world to know exactly what to say without offending someone.
So I met with my lawyer yesterday, and on her advice I wish to say the following:

Please accept with no obligation, implied or implicit, my best wishes for an environmentally conscious, socially responsible, low stress , non-addictive , gender-neutral celebration of the winter solstice holiday practiced with the most enjoyable traditions of religious persuasion or secular practices of your choice with respect for the religious / secular persuasions and/or traditions of others, or their choice not to practice religious or secular traditions at all.

I also wish you a fiscally successful, personally fulfilling and medically uncomplicated recognition of the onset of the generally accepted calendar year 2011, but not without due respect for the calendar of choice of other cultures whose contributions to society have helped make our country great (not to imply that Australia is necessarily greater than any other country) and without regard to the race, creed, colour, age, physical ability, religious faith or sexual preference of the wishee.

By accepting this greeting, you are accepting these terms:

This greeting is subject to clarification or withdrawal. It is freely transferable with no alteration to the original greeting. It implies no promise by the wisher to actually implement any of the wishes for her/him or others and is void where prohibited by law, and is revocable at the sole discretion of the wisher. The wish is warranted to perform as expected within the usual application of good tidings for a period of one year or until the issuance of a new wish at the sole discretion of the wisher.

Best Regards (without prejudice)

The italics are mine, in recognition of the fact that this piece was apparently written in Australia, where they’re currently enjoying summer.  Didn’t want to rub that in…
